Resume oxygen breathing at the shallower depth at the point of schedule interruption.

10. List 4 advantages to decompressing a diver in a chamber rather than in the water.

1) Shorter exposure time in the water. 2) Inside the chamber the divers can be maintained at a constant pressure, unaffected by the surface conditions of the sea. 3) Once divers have been recovered into the chamber another dive team can begin descent.

11. State the RNT exception rule.

In some cases, the residual nitrogen time may be longer than needed to provide adequate decompression on the repetitive dive. This situation is most likely to occur when the surface interval between the dives is short. After determining the decompression requirement for the repetitive dive the diver should recalculate the requirement by summing the bottom times of the two dives and taking the deepest depth. If the resultant table and schedule produces a longer no-decompression time or a shorter decompression time, the table and schedule with the lesser decompression obligation may be used.

12. Explain the “Safe Way Out” procedure.

If a diver is not able to reach 50 fsw in the chamber because of difficulty equalizing middle ear pressure. Compress the diver to the deepest depth he can attain initially. This will usually be less than 20 fsw Begin oxygen breathing at that depth. Continue
